[ovirt-users] Hosted engine deployment fail because host version does not match cluster version

Hello, I'm Emanuele. I'm interested in setting up a 3 node HA oVirt cluster on RHEL 8.3. Following the oVirt Gluster Hyperconvergence guide, I managed to setup a GlusterFS storage and then I started the procedure to configure a self-hosted engine via cockpit. Unfortunately, I got stack at the "Prepare VM stage". During this procedure, the automated process paused to let you verify inside the ovirt-engine that your host is OK. Since this is a brand new installation of oVirt, I have only one host configured and it is marked as not-good. The reason reported in the web page is that the host is compatible for v. 4.2, 4.3 and 4.4 but the Cluster is v. 4.5. I tried to execute the upgrade procedure on the host but it was unable to go into maintenance mode. I tried both ovirt-release44 and ovirt-release-master RPM to load the latest repository but without success. Do you have any suggestion about how to fix the self-hosted engine procedure? BTW, if I install my server with the oVirt node ISO the procedure works correctly and my host report also 4.5 into the compatibility version list. Thank you very much for your help!!!
